Track Your Perimenopause. Understand Your Changing Body.
Perimenopause is unpredictable and confusing. Hot flashes strike without warning, your mood shifts, periods become erratic, sleep disappears, and brain fog clouds your thinking. You're not broken—your hormones are transitioning. ReactLog helps you see the patterns. Correlate your symptoms with cycle timing, diet, exercise, stress, and supplements. Understand what triggers your hot flashes. Discover what helps. Share patterns with your doctor.
Perimenopause Symptoms Are Confusing and Isolating
Perimenopause doesn't announce itself clearly. You're in your 40s and suddenly you're waking up drenched in sweat at 3 AM. Hot flashes strike during meetings, leaving you flushed and humiliated. Your mood swings so violently you barely recognize yourself. Your period vanishes for three months, then returns unexpectedly. You can't sleep. Your brain feels foggy. Your joints ache. Some days you feel fine; other days you're barely functional.
The problem is you can't see the patterns. Is that hot flash caused by the spicy dinner, the stress from work, the lack of sleep, or your hormone cycle? Do your mood swings correlate with your menstrual cycle, or are they triggered by something else entirely? Is the supplement you started helping, hurting, or doing nothing? Without data, you're guessing. Your doctor might dismiss your symptoms or offer medications you're hesitant about.
Women in perimenopause often feel unseen and unheard. The medical establishment offers limited options. Hormone replacement therapy works for some, not others. Lifestyle changes help, but you don't know which ones matter for you specifically. You need evidence. You need to see your own patterns. You need validation that what you're experiencing is real and actionable.
The solution is data. Track your hot flashes, mood, period timing, sleep, and brain fog daily. Log what you eat, how much you exercise, your stress levels, and any supplements or medications. After 3-4 weeks, patterns emerge. You discover which foods trigger hot flashes. You see which supplements help with mood or sleep. You understand your cycle even when it's irregular. You have concrete evidence to discuss with your doctor.
How It Works in 3 Steps
Turn confusion into clarity. Start tracking your perimenopause journey today.
Log Your Symptoms Daily
Each day, record your perimenopause symptoms: hot flashes (frequency, intensity, time of day), night sweats, mood, anxiety levels, period status, sleep quality, brain fog, and any physical symptoms. Takes just 2-3 minutes. Add notes about diet, exercise, stress, and supplements to complete the picture.
Track Your Context
Log what might influence your symptoms: meals eaten, workouts, stress levels, supplement doses, medications, and life events. ReactLog makes logging frictionless with quick sliders and toggles. The richer your context, the clearer your patterns will be.
Discover Your Patterns
After 2-4 weeks, ReactLog's on-device analytics reveal correlations: "Hot flashes increase 60% in the week before your period," or "Your mood is 40% better on days you exercise + sleep 7+ hours." You'll see what triggers symptoms and what helps. Share these patterns with your healthcare provider.

Your Perimenopause Data Is Deeply Private
Why privacy matters when tracking sensitive health information.
Your perimenopause symptoms, period data, mood logs, and medical information are profoundly personal. You don't want this intimate health data shared, sold, analyzed by third parties, or used to target you with pharmaceutical ads. This is your life during a vulnerable transition.
Traditional health apps send your data to remote servers. Your health information becomes a commodity. It's sold to data brokers, used for research, shared with insurance companies and pharmaceutical companies. Even companies that promise privacy sometimes sell data when their business model demands it.
ReactLog works differently. We have no data to sell because we don't collect any:
- No backend servers — Your perimenopause data lives on your device only. No cloud, no remote processing, nothing.
- No data collection — We don't track what you log, how often you use the app, or what symptoms you experience.
- No analytics or telemetry — We don't send usage data to third parties.
- No account required — You don't need to create a login. No email, no identity verification, no account to compromise.
- Face ID/Touch ID security — Your perimenopause data is locked behind biometric security on your device.
- You own your data — Export your data anytime, in any format. It's entirely yours.
We're a paid app, not an ad-supported service. We charge you directly so we don't have to monetize your data. Our incentives align with yours: we want you to trust ReactLog with your most private health information.
Frequently Asked Questions
How can tracking help me understand my perimenopause symptoms?
By logging your hot flashes, mood, period timing, sleep quality, brain fog, and physical symptoms daily alongside your diet, exercise, stress levels, and supplements, ReactLog detects patterns you might miss. For example: "Your hot flashes increase 60% in the week before your period," or "Night sweats are worse on days you skip exercise," or "Your mood is 40% better when you sleep 7+ hours." These correlations help you identify triggers and plan interventions with your doctor.
What perimenopause symptoms can I track?
Any symptom you experience during perimenopause. Hot flashes (frequency, intensity, duration, time of day), night sweats, mood swings, anxiety, irritability, irregular periods, menstrual flow changes, sleep disruption, brain fog, joint pain, heart palpitations, headaches, vaginal dryness, and any other symptoms relevant to your transition. ReactLog supports custom entries so you can track symptoms unique to your experience.
How long until I see patterns in my perimenopause tracking data?
Most users start seeing meaningful correlations after 2-4 weeks of consistent daily tracking. Because perimenopause involves hormonal cycles, tracking across at least one full menstrual cycle (even if irregular) provides better pattern recognition. Some patterns appear quickly; others take 6-8 weeks. Consistency matters more than duration—tracking every day gives you clearer patterns than sporadic logging.
Can I share my perimenopause data with my doctor?
Yes. Your perimenopause data is stored only on your device, so you have complete control over it. You can export reports, take screenshots of your patterns and correlations, and share them with your healthcare provider. This gives your doctor concrete evidence of your symptom patterns, triggers, what makes things worse or better, and how treatments are working. Many doctors find this data invaluable for making treatment decisions.
Is my perimenopause and personal health data truly private?
Absolutely. ReactLog has no backend servers and zero data collection. Your perimenopause symptoms, period data, mood logs, sleep tracking, brain fog notes, stress levels, and all personal health information never leave your iPhone. We use only on-device processing. You can lock the app with Face ID or Touch ID for an additional security layer. Your perimenopause journey is completely private, and we have no access to it.
